How do you explain air to a child?
In addition to nitrogen and oxygen, air consists of small amounts of the gases argon, neon, helium, and methane. Besides gases, air also contains water vapor, dust, pollen, and bacteria. The water vapor in air is the source of rain and snow. The oxygen in air comes from plants.
What are the uses of air?
Air – Important and Different Uses of Air. In aerobic respiration, animals need to breathe the oxygen in the air. In breathing, we inhale oxygen which reaches the lungs and from lungs blood capillaries absorb oxygen and carbon dioxide is breathed out into the air. Plants need carbon dioxide for photosynthesis.
What is air what does the air contain?
Air is the invisible mixture of gases that surrounds the Earth. Air contains important substances, such as oxygen and nitrogen, that most species need to survive. Standard Dry Air is made up of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon.
What are the characteristics of air for kids?
Let’s review everything we learned about air, or the mixture of gases, water vapor, and other materials.

What are some interesting things about the air?
Air is mostly gas. Air isn’t just gas. Air is important for living things. Carbon dioxide in the air can be both good and bad. Air also holds water. Air changes as you go up, up, up. Air is a protective cushion. There is life in the air. Air can move fast and far. Air pollution can ruin your outdoor plans.
Why are we lucky to have air in our atmosphere?
On Earth, we’re pretty lucky to have an atmosphere filled with air. The air in our atmosphere acts as insulation, keeping the Earth from getting too cold or too hot. Ozone, another type of gas in the air, also protects us from too much sunlight. Air in the atmosphere can also protect us from meteoroids.
How are living things affected by air pollution?
These are major contributors to air pollution. Air is important for living things. People need to breathe, and so do lots of other animals—and plants! Breathing is part of a process called respiration. During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide.
What are the properties of air in the sky?
Properties of Air. If you breathe in the air that is higher in the sky, meaning that it is at a higher altitude than the air you are used to breathing, you will notice a definite difference. You see, air gets thinner as you get higher in the atmosphere so you are getting less oxygen than normal.
